Since bbf4b79, we stopped shipping /etc/default/useradd, and therefore
install of shadow does not auto-create /etc/default. So when useradd
tries to save a new default, it needs to create the directory.
In 9eb191edc4a625bb68e827b18638f5b5816cb30c I included a free() that
frees the members variable, which in turn causes the comma_to_list()
function to return an array of empty elements. The array variable holds
a list of pointers that point to offsets of the members variable. When
the function succeeds freeing members variable causes the elements of
the array variable to point to an empty string.
This is causing several regressions in our internal testing environment.
So, I'm reverting the change.

libmisc/salt.c: Use crypt_gensalt(), if available in libcrypt.
Most Linux distributions, including Fedora and RHEL 8, are shipping
with libxcrypt >= 4.0.
Since that version of libxcrypt the provided family of crypt_gensalt()
functions are able to use automatic entropy drawn from secure system
ressources, like arc4random(), getentropy() or getrandom().
Anyways, the settings generated by crypt_gensalt() are always
guaranteed to works with the crypt() function.
Using crypt_gensalt() is also needed to make proper use of newer
hashing methods, like yescrypt, provided by libxcrypt.

In a previous commit we introduced /dev/urandom as a source to obtain

Almost all systems provide functions to obtain random bytes from

struct subordinate_range is pretty closely tied to the existing

So introduce a 'struct subid_range' which is only the start and

libsubid: don't print error messages on stderr by default
Closes #325
Add a new subid_init() function which can be used to specify the
stream on which error messages should be printed. (If you want to
get fancy you can redirect that to memory :) If subid_init() is
not called, use stderr. If NULL is passed, then /dev/null will
be used.
This patch also fixes up the 'Prog', which previously had to be
defined by any program linking against libsubid. Now, by default
in libsubid it will show (subid). Once subid_init() is called,
it will use the first variable passed to subid_init().
When uid 0 maps host uid 0 into the child userns newer kernels require
CAP_SETFCAP be retained as this allows the caller to create fscaps that
are valid in the ancestor userns. This was a security issue (in very
rare circumstances). So whenever host uid 0 is mapped, retain
CAP_SETFCAP if the caller had it.
Userspace won't need to set CAP_SETFCAP on newuidmap as this is really
only a scenario that real root should be doing which always has
CAP_SETFCAP. And if they don't then they are in a locked-down userns.
(LXC sometimes maps host uid 0 during chown operations in a helper
userns but will not rely on newuidmap for that. But we don't want to
risk regressing callers that want to rely on this behavior.)

Currently, supplying a relative path via the --prefix flag to the
useradd command triggers a bug in the creation of home directories. The
code seems to unintentionally prepend a leading "/" to all paths,
quietly transforming a relative prefixed home path into an absolute
path. This can be seen in the following strace logs from running
"useradd --create-home --prefix tmp/root squat":
```
access("tmp/root//home/squat", F_OK) = -1 ENOENT (No such file or directory)
access("/mp", F_OK) = 0
access("/mp/root", F_OK) = 0
access("/mp/root/home", F_OK) = 0
access("/mp/root/home/squat", F_OK) = -1 ENOENT (No such file or directory)
mkdir("/mp/root/home/squat", 000) = 0
chown("/mp/root/home/squat", 0, 0) = 0
chmod("/mp/root/home/squat", 0755) = 0
chown("tmp/root//home/squat", 1000, 1000) = -1 ENOENT (No such file or directory)
chmod("tmp/root//home/squat", 0700) = -1 ENOENT (No such file or directory)
```
Note that the relative path is correctly probed in the beginning and it
is only during the recursive creation that the path is turned into an
absolute path. This invocation results in the creation of a "/mp"
hierarchy in the root of the filesystem.
Similar problems occur when using `--prefix ./tmp/root`.
This commit fixes the handling of relative paths by not assuming that
the given path is anchored with a "/".

Closes #154
When starting any operation to do with subuid delegation, check
nsswitch for a module to use. If none is specified, then use
the traditional /etc/subuid and /etc/subgid files.
Currently only one module is supported, and there is no fallback
to the files on errors. Several possibilities could be considered:
1. in case of connection error, fall back to files
2. in case of unknown user, also fall back to files
etc...
When non-files nss module is used, functions to edit the range
are not supported. It may make sense to support it, but it also
may make sense to require another tool to be used.
libsubordinateio also uses the nss_ helpers. This is how for instance
lxc could easily be converted to supporting nsswitch.
Add a set of test cases, including a dummy libsubid_zzz module. This
hardcodes values such that:
'ubuntu' gets 200000 - 300000
'user1' gets 100000 - 165536
'error' emulates an nss module error
'unknown' emulates a user unknown to the nss module
'conn' emulates a connection error ot the nss module
Changes to libsubid:
Change the list_owner_ranges api: return a count instead of making the array
null terminated.
This is a breaking change, so bump the libsubid abi major number.
Rename free_subuid_range and free_subgid_range to ungrant_subuid_range,
because otherwise it's confusing with free_subid_ranges which frees
memory.

try again to fix libmisc sharing problem
Issue #297 reported seeing
*** Warning: Linking the shared library libsubid.la against the
*** static library ../libmisc/libmisc.a is not portable!
which commit b5fb1b38eea2fb0489ed088c82daf6700e72363e was supposed
to fix. But a few commits later it's back. So try to fix it
in the way the bug reporter suggested. This broke builds some
other ways, namely a few missing library specifications, so add
those.
